President Donald Trump betrayed what many believed was a clue about a magnetic resonance imaging he underwent last month.

Minnesota Gov. Tim Walz challenged the 79-year-old president to release findings from the MRI test after Trump slurred him as "ret*rded," and Trump doubled down on the ableist slur when asked for comment Sunday evening aboard Air Force One, and then a reporter asked for specifics about that exam.

“What part of your body was the MRI looking at?” the reporter asked

“I have no idea, it was just an MRI- what part of the body?" Trump fired back. "It wasn’t the brain because I took a cognitive test and I aced it — I got perfect part, which you would be incapable of doing! Goodnight, everybody. You, too!”

Many social media users felt the president may have volunteered too much.

"It was for sure an MRI on his brain, right?" said "The Young Turks" co-host Jordan Uhl.

"If Trump denies they did a MRI of his brain, then it sounds like they did a MRI of his brain," opined Bluesky user Zobear.

"90% probability MRI was on his brain," posted the Angry Staffer account. "Trump also says it’s ok to release it. Journalists, do your thing."

"If you had an MRI and didn’t know what it was taken for, it definitely was the brain," agreed Bluesky user bd-nola.

"My brain is so perfect that I don't know why I got an MRI," joked journalist Thor Benson.

"Tell us you had a brain MRI without saying you had a brain MRI," said comedian Hayden Black.

"Trump’s reply to what the MRI scanned being 'it’s not the brain' is a dead giveaway it was definitely the brain," observed Bluesky user kbethany.

Even the Associated Press joined in the pile-on, noting in its headline Trump "doesn't know what what part of his body was scanned."
